Investigations & Hotline Allegations

Law enforcement personnel from various agencies investigate allegations of criminal misconduct that might compromise or involve U.S. Government programs and operations. Each agency maintains their own hotline to receive complaints specific to their agency providing a confidential, reliable means to report suspected violations of law, rule, or regulation; mismanagement; gross waste of funds; or abuse of authority.

Investigators and Partners Involved

The Special Inspector General and the Lead Inspector General agencies coordinate Operation Atlantic Resolve (OAR) investigations with their partners in the Fraud and Corruption Investigative Working Group (FCIWG) and other forums. The FCIWG consists of representatives from: the Defense Criminal Investigative Service (DCIS, the DoD OIG's criminal investigative component), the Department of State OIG, the USAID OIG, the U.S. Army Criminal Investigation Division (CID), the Naval Criminal Investigative Service (NCIS), the Air Force Office of Special Investigations (OSI), the Federal Bureau of Investigation (FBI), and Homeland Security Investigations (HSI).

The Special IG agencies have positioned criminal investigators in Germany, Poland, and Ukraine to investigate allegations of fraud, corruption and potential diversion of weapons or technology. DCIS agents in Kyiv continue working jointly with the U.S. Embassy partners and Ukrainian authorities, to assess any reported discrepancies related to accounting for weapons and military equipment requiring enhanced end use monitoring.

Investigations

In addition to investigating allegations of misconduct, investigators identify, coordinate, and de-conflict fraud and corruption investigations; share best practices and investigative techniques; and coordinate proactive measures to detect and deter the criminals who would exploit U.S. Government assistance to Ukraine.

Hotline Allegations

Each OIG Hotline office evaluates complaints received through the hotlines and forwards them to the respective investigative entity for review and investigation.

MOUs Increase Cooperation with Ukraine

The Special IG has discussed the memoranda of understanding (MOUs) that have been signed between the DoD, State, and USAID OIGs and their Ukrainian counterparts, including the National Anti-Corruption Bureau of Ukraine (NABU), Main Inspectorate, and Specialized Anti-Corruption Prosecutor’s Office (SAPO), to formalize information sharing in support of criminal investigations and oversight work. The memoranda of understanding (MOUs) amongst the OIGs and their Ukrainian counterparts - including the National Anti-Corruption Bureau of Ukraine (NABU), Main Inspectorate, and Specialized Anti-Corruption Prosecutor’s Office (SAPO) - have facilitated cooperation and information sharing in support of criminal investigations and oversight work.

DoD OIG investigators have routinely employed these MOUs to establish relationships with the Ukrainian Main Inspectorate and other investigative partners, enabling the exchange of information and prompt addressing of inquiries related to U.S. investments in Ukraine. DoD OIG investigators reported that they routinely employ these MOUs as a mechanism for the exchange of information with their Ukrainian counterparts. DoD OIG personnel met regularly with the Ukrainian Ministry of Defense and other investigative partners, and through these relationships, facilitated by the MOUs, addressed inquiries promptly. DoD OIG personnel continue to build relationships with Ukrainian government entities to facilitate efforts to account for U.S. investments in Ukraine.
